Puppet is using predictable temporary file names when downloading
Mac OS X package files. This allows a local attacker to either
overwrite arbitrary files on the system or to install an arbitrary
package.

When handling requests for a file from a remote filebucket, Puppet
can be tricked into overwriting its defined location for filebucket
storage. This allows an authorized attacker with access to the Puppet
master to read arbitrary files.

Puppet is incorrectly handling filebucket requests. This allows an
attacker with access to the certificate on the agent and an unprivileged
account on Puppet master to execute arbitrary code via crafted file
path names and making a filebucket request.
